Expert Autonomic Specialists
Our private autonomic testing centre is led by highly experienced specialists who understand the complexity of dysautonomia and are committed to rapid, accurate diagnosis.
Are You Experiencing These Symptoms?
Autonomic dysfunction can show up in many ways. If any of these sound familiar, testing can help find the cause.
Why Autonomic Testing?
Your autonomic nervous system controls heart rate, blood pressure, digestion, temperature and sweating. When it malfunctions, symptoms are widespread but standard tests often come back “normal.” Autonomic testing finds what standard tests miss.
Our Comprehensive Testing Protocol
Standardised protocols, interpreted by a neurologist, with the report within a week.
📊 Active Stand Test with Recovery BP
Blood pressure and heart rate recorded lying down, as you actively stand, and again on return to lying (recovery blood pressure) — to detect POTS and orthostatic hypotension.
💓 Heart Rate Variability
Deep-breathing test assessing the autonomic balance between sympathetic (fight or flight) and parasympathetic (rest and digest) responses.
🫁 Valsalva Maneuver
Assesses cardiovagal function via the Valsalva ratio, from the heart-rate response to controlled expiratory strain.
🤼 Isometric Handgrip
A sustained handgrip drives a reflex rise in blood pressure through the sympathetic nervous system; the rise provides supplementary information about adrenergic function.
✋ SudoScan Technology
Modern, painless testing for small fiber neuropathy and sudomotor dysfunction. No needles, no heating chambers — sensor plates, under 10 minutes.
What You Get
What the report gives you
Autonomic function testing is a clinical test, not a neurological consultation. Once testing is complete you receive a comprehensive report with expert interpretation. Your treating doctor uses it to decide what happens next; a consultation with Dr Granot can be arranged separately.
Quantified results
Haemodynamic, parasympathetic, sympathetic adrenergic and sudomotor domains, each measured and reported separately.
Interpretation in context
What the pattern means, and where it sits against normal ranges — written for the doctor who is managing you.
Sent to your doctor
The report goes to your GP or specialist, who interprets the findings and decides on management. Repeat testing can be arranged if they request it.
Frequently Asked Questions
How long is the wait for private autonomic testing?
Appointments are usually available within weeks, not 6–12 months. Testing is completed in one session and a written report is provided within about one week.
What conditions does autonomic testing diagnose?
Autonomic testing supports diagnosis of POTS, orthostatic hypotension, small fiber neuropathy, cardiovagal dysfunction, and other forms of dysautonomia. It provides objective data that standard tests usually miss.
Is the testing painful?
No. The standard autonomic tests are non-invasive. SudoScan uses sensor plates — no needles, no heating chambers. Blood-pressure and heart-rate recording uses a blood-pressure cuff and ECG electrodes. The most uncomfortable part is the active stand itself, which is the test.
Do I need a referral?
A referral is not required for autonomic testing. Your GP's details are helpful so we can send a copy of the report to your doctor. Please contact us with any questions.
Will I get a Medicare rebate?
This is a private specialist service. Autonomic function testing does not attract a Medicare rebate; none is available for this testing. Please contact us for current testing fees.

Comprehensive Autonomic Function Testing in One Session
Active stand test with recovery blood pressure, HRV with deep breathing, Valsalva, isometric handgrip, and SudoScan in a single appointment. Reports for referring doctors typically within one week. Combined neurology and cardiology interpretation.
When to Refer
Common indications where autonomic function testing meaningfully changes management.
Orthostatic intolerance
Symptoms on standing — lightheadedness, palpitations, brain fog — with or without measured tachycardia or hypotension in clinic. Identifies POTS and the heart-rate rise on active standing.
Orthostatic hypotension
Sustained postural fall in blood pressure, or symptomatic orthostatic intolerance, where objective characterisation of the orthostatic response and adrenergic baroreflex function is needed.
Small fiber neuropathy
Burning feet, length-dependent sensory symptoms, abnormal sweating, autonomic features with normal nerve conduction studies. SudoScan provides quantitative sudomotor data.
Diabetic autonomic neuropathy
Resting tachycardia, postural symptoms, gastroparesis, erectile dysfunction or unexplained falls in a diabetic patient.
Parkinsonian / synucleinopathy
Suspected MSA, pure autonomic failure, or significant autonomic features in Parkinson's disease. Objective quantification of severity and pattern.
Post-viral / chronic fatigue with autonomic features
Including post-COVID dysautonomia. Quantifies the autonomic component and distinguishes from deconditioning where possible.
Autoimmune & paraneoplastic
Sjögren's, autoimmune autonomic ganglionopathy, paraneoplastic syndromes — where autonomic involvement needs objective documentation.
Pre-treatment baseline
Quantitative baseline before starting agents that may affect autonomic function, or as part of fitness assessment.
Tests Performed
Standard battery completed in a single session. Additional cardiovascular workup available where indicated.
📊 Active stand test with recovery blood pressure
Non-invasive blood pressure and ECG recorded supine, throughout active standing, and on return to lying (recovery blood pressure). Quantifies orthostatic blood pressure and heart rate responses for POTS, orthostatic hypotension and delayed orthostatic patterns, plus adrenergic baroreflex function.
💓 Heart rate variability with deep breathing
Paced respiration at standard rates to quantify respiratory sinus arrhythmia. Primary measure of cardiovagal (parasympathetic) function.
🫁 Valsalva manoeuvre
Standardised forced expiration against resistance. Yields the Valsalva ratio (cardiovagal).
🤼 Isometric handgrip test
Sustained isometric handgrip raises blood pressure through a sympathetically mediated reflex; the magnitude of the rise provides supplementary information about adrenergic function. A blunted response indicates adrenergic failure.
✋ SudoScan / sudomotor function
Electrochemical skin conductance from sensor plates — no needles, no thermoregulatory sweat test required. Quantitative bilateral hand and foot indices for small fiber and sudomotor assessment.
What You Receive
Reports are written for referring doctors — quantitative, contextualised, and actionable.
Structured quantitative report
Results for each domain (haemodynamic, cardiovagal, sympathetic adrenergic, sudomotor) with reference ranges and pattern recognition. Composite autonomic severity is reported where appropriate.
Clinical interpretation
Findings placed in the context of the referral question. Diagnostic impression where appropriate (e.g. POTS, OH, small fiber neuropathy pattern) rather than a list of numbers.
Turnaround
Single-session testing. Written report typically within one week. Same-week phone call for urgent or unexpected findings.
Protocols and Methodology
Standardised protocols, interpreted by a neurologist, with the report within a week.
Blood pressure & ECG
Non-invasive blood-pressure recording with synchronous ECG throughout the protocol.
Standardised protocols
Active stand with recovery blood pressure, paced breathing protocols, standardised Valsalva pressures, isometric handgrip — results comparable across visits and against published reference data.
SudoScan electrochemical assessment
Quantitative sudomotor function from hand and foot plates. Sensitive to small fiber autonomic involvement and tracks change over time.

Clinical FAQ
When should I refer a patient for autonomic testing?
Orthostatic intolerance with tachycardia or hypotension; postural / orthostatic hypotension; small fiber neuropathy symptoms (burning feet, abnormal sweating, length-dependent sensory loss); suspected central dysautonomia or autonomic failure (e.g. multiple system atrophy, Parkinson's disease); suspected dysautonomia in diabetes, amyloidosis, autoimmune conditions, or post-viral syndromes; and unexplained chronic fatigue with autonomic features.
What tests are performed?
The standard battery includes an active stand test with recovery blood pressure (blood pressure and heart rate, supine, on active standing and on return to lying), heart rate variability with deep breathing, Valsalva manoeuvre, isometric handgrip, and SudoScan for sudomotor / small fiber assessment. Additional cardiovascular testing is available where indicated.
What is the turnaround time for reports?
Testing is completed in a single session. Written report typically within one week, with same-week communication for urgent or unexpected findings.
What is in the report?
Quantitative results for each domain (haemodynamic, parasympathetic, sympathetic adrenergic, sudomotor), interpretation in the clinical context, diagnostic impression where appropriate, and and any technical limitations. Management decisions rest with your treating doctor.
How do I refer?
Standard specialist referral to Dr Ron Granot (Neurology) or Dr Jason Kaplan (Cardiology), Suite 301, 251 Oxford Street, Bondi Junction NSW 2022. Telephone 02 9388 0615 or use the booking form. Please include the clinical question and relevant prior investigations.
Are there any contraindications?
Active acute illness, recent vagally-mediated procedures, or inability to tolerate postural changes may require deferral. SudoScan is generally well-tolerated but contraindicated in pregnancy and in patients with implanted electronic devices — please flag these on referral.
Should the patient stop their medications before testing?
It depends on the clinical question. For most baseline assessments, patients can continue usual medications. If you specifically need to characterise autonomic function off treatment, we will discuss medication washout protocols on a case-by-case basis. Please contact us if unsure.
